The global population will cross-over the 8 billion mark during 2023. In addition, new data indicates the number of over 60s will top 1 billion. Figures also show there are considerably more men than women currently living.

Brown dwarf stars are rare and remain a mystery to astrophysists. The stars are "brown" when viewed through a telescope because they cannot burn enough nuclear fuel to shine as brightly as other stars. A new study sheds a little more light.

Scientists are virtually sure they have found a new planet at the outer edge of our solar system. Sometimes called Planet X or Planet Nine, it is believed to be lurking in the little-known Kuiper belt far beyond Pluto.

Astronomers have observed a magenta planet the size of Jupiter about 57 light years from Earth. It’s the smallest planet ever detected outside the Solar System using direct imaging techniques.

Scientists said the smaller moon have only survived a few million years before it collided with the one we see today, leaving just one. Landscapes on the current moon are the remains of the smaller moon from the collision.

Using new observation of Gliese 667C, astronomers found seven planets circling a star, including three super-Earths orbiting in the habitable zone. Gliese 667 is a triple-star system in the constellation of Scorpius that has masses smaller than Sun.

NASA’s Kepler Space Telescope managed to capture the dimming of a star more than 215-light-years away, alerting scientists to the presence of a tiny planet passing between the star and Earth.

The image shows where more or less heat, in the form of long-wave radiation, is emanating from the top of the Earth's atmosphere.

This artist's conception illustrates Kepler-22b, a planet known to comfortably circle in the habitable zone of a sun-like star. It is the first planet that NASA's Kepler mission has confirmed to orbit in a star's habitable zone -- the region around a star where liquid water, a requirement for life on Earth, could persist. The planet is 2.4 times the size of Earth, making it the smallest yet found to orbit in the middle of the habitable zone of a star like our sun. (NASA)

This map-projected view of Ceres was created from images taken by NASA's Dawn spacecraft during its initial approach to the dwarf planet, prior to being captured into orbit in March 2015. The map is an enhanced color view that offers an expanded range of the colors visible to human eyes. Scientists use this technique in order to highlight subtle color differences across Ceres. This can provide valuable insights into the physical properties and composition of materials on the surface

NASA's Spitzer Space Telescope has found that the hottest part of a distant planet, named upsilon Andromedae b, is not under the glare of its host star as might be expected.
